PRICE-IN DICATING ATTACHMENT FOR WEIG HING-SCALES.

SPECIFICATION forming part of Letters Patent No. 410,389, dated Septelnbzr 3, 1889.

Application filed November 23, 1888. Serial No. 291,668. (No model.)

To @ZZ whom i6 may concern.-

Ile it known that I, LUCIUS Ii. VANDS, of lest Shokan, in the county of lllster and State of New York, have invented a new and Improved Priee-Indicating Attachment for Scales, of which the following' is a full, clear, and exact description.

The object of this invention is to provide an attachment for scales whereby the value of any fraction of a given unit of weight at any price per unit from l to lOO will be indicated; and to this end the invention consists of two indicators, preferably cone-shaped, that are divided into sections by lines that run at right angles to the axes of the cones, each section being in turn divided by lines that are substantially parallel with the axis of the cone, strips arranged in connection with the cones, the strips being divided into sections corresponding in width to the conesections, said sections being numbered from 2 upward upon one strip, all the even linmbers appearing on said strip, while the sections of the other strip are numbered from l upward, all of the odd numbers appearing on this strip. To facilitate the reading of the cones, I provide wires which run in close proximity to the surfaces of the cones and directly above and parallel with the axes of the cones, and in connection with the cones I provide a mechanism whereby the cones are each rotated by the movement of a balancing-weight, the movements of the cones being in proportion to the distance traversed by the weight upon its sul'iporting-beam.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar iigures and letters of reference indicate corresponding parts in all the views.

Figure l is a plan view of a portion of a counter-scale, representing` the saine as it appears when provided with my price-indicat ing attachment. Fig. 2 is a side view of the scale. Fig. 8 is a cross-sectional view on line 3 3 of Fig. l. Fig. 4@ is a plan view of the cone arranged in connection with the bar or strip upon which the even numbers appear, views 3 and 4 being on an enlarged scale.

In the drawings, 10 represents the standard, l1 the beam, l2 the scale-pau, and l2 the plate or weight-support of an ordinary eounter-scale.

In a) l yinw` 1n f attachment I 'ournal e 'linders or cones li and l5 between the longitudinal sections, b of the beam ll, the journals extending through the forward section l), as shown at c, and to these extending joui nal ends I secure pulleys 17, Figs. l and 4, which carry a metallic belt 1S. .Between the parallel lengths of the belt 1S, I attach an auxiliary'beam 20, said auxiliary beam being carried by the forward section l), Fig. i?, of the main beam Il. Upon the beam 20, I mount a slide 23, (shown best in Figs. 2 and 3,) having a threaded shank d, which passes downward through an aperture formedin the lower length of the belt 18, the lower end of the shank being engaged by a nut c', by means of which the tension of the belt may be regulated, the nut being turned upward when it is desired to tighten the belt. From the slide 23, I suspend a weight 2l by means of a double hook 22, which engages projections f, Fig. 3, that extend outward from the sides of the slide.

The cone 1l is divided transversely into fifty sections e, and these sections are divided circumferentially as follows: The sections nearest the base of the cone or the far side of the cylinder are divided into ninety-nine subdivisions, which said subdivisions are divided into periods of five, numbered from zero up to 95, the last period being divided into four spaces. The eleventh section from the base of the cone or the back of the cylinder is divided into seventy-nine subdivisions, the periods being numbered from zero up to 75, and the last period being divided into four spaces to complete the seventy-nine subdivisions of this particular con e-section, and this plan is followed in dividing each cone-section, a corresponding plan being` followed in the division of the cone l5. Each of the spaces, supposing the unit of value to be one dollar, will represent one cent. In fact, each of these sections must be divided into as many parts circumferentially as there are units in its de nominating number, the divisions bein g preferably made by dots and elongated marks, as shown in the drawings, the numbering of all spaces starting upon a line that is exactly IOC) be just to one side of these wires.

parallel with the axis of the cylinder or cone, as will be readily understood.

Above the cone 14 there is mounted a strip, 25, that is divided into fifty spaces, numbered from 1 to 99, while above the cone 15 thereis mounted a strip 2P, divided into iifty spaces, that are numbered from 2 to 100, the spaces of the strips registering with the spaces of the cones. These strips are secured to the beam in any proper manner, but preferably by screws, as shown best at w in Fig. 3, the strips being bent so as to rest closely above the cylinder or cone faces.

To facilitate the reading of the concs, l arrange wires 27', which run in close proximity to the cone-surfaccs, exactly above and parallel with the axes of the cones, one of these wires being employed for each cone, and when the scale is at rest and the beam balanced the zero-line upon cach cone or cylinder will Let it be supposed that the scale -in connection with which my attachment is arranged is designed to weigh pounds and that the unit of value is one dollar; then in adjusting the attachment the beam 2O and the weight- 21 should be so proportioned that if the weight be moved to the position in which it is shown in Fig. 2 to the opposite end of its beam it would counterbalance one pound placed in the pan 12.

Suppose it is desired by means of my attachment to ascertain the value of a quantity of merchandise worth fort-y cents a pound. The merchandise is placed in the scale-pan 12, and pound counterbalancing-weights are placed upon the scale-plate orweight-support12 until it is ascertained that the merchandise weighs, we will say, between five and six pounds. rFhen, after this approximate weight is ascertained, the weight 21 is moved along the beam 2O in the direction of the arrow shown in Fig. 2, and in so moving` it will carry the belt 18 in the direction of its arrow, and as the belt moves, as indicated, the cones or cylinders 14 and 15 will be rotated, a full rotation of the cones being brought about by moving the slide 23 from one end of its beam to the other, as has been hereinbefore explained; but as the slide 23 is moved, as jnstdescribed, it will be brought to a point at which the weight 2l, in connection with the weights on the scale-pan or weight-support 12, will eX- actly counterbalance the merchandise in the scale-pan 12. Then, if we glance at the cone 15 and read the number beneath the wire 27 that appears opposite the division numbered 40 on the strip 2G, we will find the value of the fractional portion of a pound of the niatcrial contained in the scale-pan 12. Let us suppose that this fractional part is one-half of a pound. In that case the slide 23, and with itthe weight 21, would have moved onehalf of the distance toward the right-hand end of its beam, and consequently a one-half turn would have been imparted to the cone, thus bringing the mark 2O beneath the wire 27; and supposing that there were live pound counterbalancing-weights placed in the scaleplate 12 we would know that the value of the goods would be two dollars and twenty cents.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. ln a price-indicating attachment, the combination, with a revoluble indicator divided longitudinally into a number of sections, said sections being proportionately divided, of a strip divided into numbered sections, a counterbalancing-weight, and connections, substantially as described, between the indicator and weight, whereby when the weight is moved the indicator will be turned, as and for the purpose stated.

2. The combination, with indicators divided substantially as described, of numbered strips arranged in connection with said indicators, pulleys carried by the indicator-journals, a belt carried by the pulleys, a weight, and a beam, the weight being connected to one length of the belt, substantially as described.

3. In a price -indicating attachment, the combination, with indicators divided longitudinally into sections, the sect-ions of one indicator being divided proportionately from 1 to 99 and the sections of the other indicator being divided proportionately from 2 to 100, strips divided into sections which correspond with the in dicator-sections, the sections of one of the strips being numbered from 1 to 90 and the sections of the other strip from 2 to 100, pulleys carried by the indicator-journals, a belt carried by the pulleys, and a weight connected to the belt and suspended from a beam, substantially as described.

4. In a priceeindicating attachment, the combination, with indicators 14 and 15, of strips 25 and 2U, wires 27, pulleys 17, carried by the indicator-journals, a belt 18, arranged in connection with the pulleys, a beam 20, a weight suspended from said beam, and connections between one length of the belt and the weight, substantially as described.
